| 摘 要： | 对1980至2012年广西85个县市能见度资料进行统计分析得出：广西主要城市及其周边地区能见度较低,边远山区及边境地区较高,呈现东部低、西部高的特点;广西近32a能见度年均值在14.4至18.2km之间,总体呈下降趋势.一年之中,能见度夏季高、冬季低,汛期能见度明显好于非汛期;能见度与气象要素的相关分析表明,能见度与温度、风速成正比,与压强、降水、湿度成反比.

| Abstract: | Based on the statistical analysis of visibility data from 85 conventional weather stations in Guangxi during 1980 to 2012, the results showed that the visibility was lower in major cities and their surrounding areas, but higher in remote areas and border areas. And it presented low in the east, and high visibility in the west. It appears a trend of high in summer, and low in winter during a year .The visibility in flood season is obviously better than that in non-flood season. Correlation analysis between visibility and meteorological elements indicate that the visibility has positive correlation with wind velocity, on the contrary it has negative correlation with temperature. |
